Oh well, what can you expect before 8 a.m. on a Saturday? At least we both asked for exactly the same thing.
I'm hoping we can document the clamping (do you use a long lateral clamp across the side plates to close up the gap in the broken rail?), the way the reinforcing plate fits (welding room around the outside, clear of the flanges?), and several progress shots of the stitch-welding, showing the pattern of welds, and the distance between welds (usually equal amounts of weld and space, but let's see Jarrad's approach). Then some pics of the alignment check with the gauge would be good. If it were me I think I'd do the welding with the front and rear rollers in place, and I'd check the alignment after the first pair of stitches, then every few stitches afterward. If the process is done correctly you should find it is pulling itself back straight whenever the pattern of completed stitches is symmetrical. If I'm doing it, on the other hand, it's out with the angle grinder after the first couple of stitches because it isn't precisely correct.
